PHASE-COM PLETING DEVICE.

SPECIFICATION forming part of Letters Patent No. 552,553, dated January7, 1896.

Application filed March 28, 1893.

.To all whom it may concern,.-

Be it known that l, JAMEs T. SIBLEY, of Clinton, Huron county, Provinceof Ontario, Dominion of Canada, have invented a new anduseful,Phase-CompletingDevice, of which the following is aspeciiication.

Figure l of the drawings is a view of the device with the switch liftedout of contact and in position to be forced down by an impulse throughthe coils of the magnet; Fig. 2, a view of the same with the switch downand contacts closed and the switch locked in place, the dotted linesshowing the position of the armature-lever when down and the full linesshowing the lever and its pivoted arm when it has passed behind thebracket. Fig. 3 is a view of the same with pin on end of the pivoted arml)s in position to force cut the arm d' and unlock the switch. Fig. 4 isa view of the pivoted hanger on the end of armaturelever and showingposition of the spring for operating this hanger to throw its lower endto the right; Fig. 5, a view of the pivoted hanger on center; Fig. 6, aview of pivoted hanger forced to the other side and its spring ready tothrow it back.

Viewing Fig. l, A is a frame, of wood or other suitable material,provided with the binding-posts o. a2 a3 ai. Upon this frame is suitablymounted the electromagnet B, provided with its armature-lever b/ andretractin g-spring b2. The dotted lines on Fig. 3 show the connectionswith the binding-posts and the line, so that an impulse through thecoils of the electromagnet will operate its armature-lever and a breakwill allow it to be retracted by its spring. l

The switch C is pivoted at c'. lts normal position is drawn up by thetension of the spring c2, as shown in Fig. l. On the end of this switchis placed the contact c3, made of suitable conducting material andarranged to make contact with the plate ci when forced down. Attached tothe spring is the bracket c5, and this bracket is provided on one sidewith the projection c6, and on the other side it is slightly rounded.The bracket c5 and projection c may be made in two pieces instead ofsolid, as shown in the figures. On the switch O is also placed a lug, asc7, to 3o-operate with Serial No. 467,937. (No morlel.)

a checking or locking device herein after fully explained.

Suitably pivoted to a part of the frame is the hanger D, provided withthe arms d (Z2. The lower ends of its arms are forced to the right bythe spring d3 and to the left by the downward movement of thearmature-lever b.

On the end of this armature-lever is pivoted j the arm b3, which nearits lower end is provided with a pin or projection b4. When the switchis down the arm d2 comes in contact with the lug or projection c7 andholds the switch in position until the arm is forced off of theprojection by the passage of the pin h4 between the bracket c5 and thearm cl, the action of the pivoted arm b3 is controlled by the spring b5secured to the armature-lever at one end with its other end resting onthe top of the arm. The action of this spring on the arm h3 isillustrated in Figs. 4, 5 and 6. Vhen the arm is hanging plumb thespring rests upon the plane top surface of the arm, as shown in Fig. 5.Vhen it is out of plumb, with its lower end to the left of a plumb-line,the spring rests upon the upper left-hand corner of the arm, as shown inFigs. 3 and 4. Then it is thrown to the right of a plumb-line the springrests upon the upper right-hand corner of the arm, as shown in Figs. land 6. Viewing the position of the parts, as shown in Fig. l, it will beseen that an impulse through the coils of the magnet will force down thearmaturelever and the switch until the contacts e'1 are closed, as shownin Fig. 2, which also shows in dotted lines the position of thearmature-lever and the arm b3. At this point the hanger D has beenforced out by its spring cl3 until the arm cl2 has passed above and overthe lug cl, holding the contacts c3 c4 closely together. The circuitthrough the bindingposts a3 a4 is then closed and remains closed untilit is opened by another impulse. In this closed position of the contactsthe spring b5 is resting upon the upper right-hand corner of the arm o3,as shown in Fig. 6. Then the armature-lever is released and drawn backby its spring b2 the pin lrL passes up beyond the top of bracket c5,when the spring b5 throws the arm to the left in the position shown infull lines in Fig. 2, and ready when it descends IOO to enter the pin b4behind the bracket and between it and the arm d1. When another impulseis given and the arm descends the position of the spring h5 is changedand rests upon the upper left-hand corner of the arm, as shown in. Figs.3 and 4, and in descending actuates the arm d, disengaging the arm d2from the projection c7. The switch is then thrown up by the spring c2.At the same time the action of the spring b5 on the arm b3 throws thepin h to the other side of the bracket, when it takes its position onthe seat c(5 ready for another impulse to close the contacts c3 c4.rlhus with each impulse the current in that circuit is opened or closed.

The above description represents the action of the device when used uponan open magnet-circuit and its operation in response to impulses; but itwill be seen that the same device may be used upon closed circuit byusing the retracting-spring of the armaturelever to close the contactsand the impulse through the coils of the magnet to open them.

It will also be seen that the device may be operated by hand and withoutthe use of the magnet B, and that it may also be operated in connectionwith any other device as well as a switch. For example, by connecting asemaphore or other device to the end of switchbar C it would be thrownto safety by one movement of the switch-bar in a forward or downwarddirection, and with the next forward movement of the actuating-arm D thelocking devices would be released and allow the semaphore to be returnedto danger.7

That I claim, and desire to secure by Let-l ters Patent, is-- l. In aphase-completing device provided with an actuating arm therefor, havinga forward and a backward movement, and devices for impelling the arm aiixed distance to thereby complete the throw of the phase-completin gdevice, in combination with locking devices actuated by said arm in itsforward movement whereby the phase-completing device is locked andretained in position while the arm is withdrawn to complete its backwardmovement, and releasing devices actuated by the next forward movement ofsaid arm an in combination with locking devices actuated by said arm inits forward movement, whereby the phase-completing device is locked andretained in position,while the arm is withdrawn to complete its backwardmovement, and releasing devices actuated by thc next forward movement ofsaid arm an equal distance to thereby throw out the locking devices, andallow the retractile spring to restore the phasecompleting device tostarting point.

3. In a circuit changing device the coinbination with a switch as Cprovided with the bracket c5, of an armature leverprovided with apivoted arm as h3, the spring b5, arranged in. connection therewith, tothrow the arm h3 to one side or the other of the bracket as required.

4. In a phase-completing device provided with an actuating arm thereforhaving a forward and a backward movement and devices for impelling thearm to complete the throw of the phase-completing devi ce an equaldistance with each forward movement, in ccmbination with automaticlocking devices to hold and retain the phase-completing device at theend of its course while the impelling devices are withdrawn, and aguiding device, whereby the impelling devices are directed to actuatethe phase completing device to the end of its course, and to unlock andrelease the same at the next forward movement.
